One of my favorite misinformed "opinions" about the 9/11 event is the hilariously overblown claims that part of the reason the Twin Towers collapsed was the extremely high temperature of burning jet fuel caused the steel structures to warp and partially melt. Anybody that knows anything about both fire and metal should recognize this is a complete fallacy and utter lunacy. Steel is a conductor of heat, it isn't something that just absorbs it and melts down. Have you ever tried to burn a paper clip, or a nail? Fire just doesn't work like that.
